Conveyor pulley lagging can improve the operation of the conveyor system, increase friction, and prevent the conveyor belt from running off. Common pulley lagging methods mainly include hot vulcanization, cold bonding and Weld on (bolt on ) lagging. These types of lagging methods have their own advantages and disadvantages. When choosing, they should be selected according to working conditions and actual needs.
Hot vulcanization pulley lagging
Advantages: Hot vulcanized lagging has been in use the longest and is the most mature technology for pulleys of all sizes and shapes. When the diameter of the drum is small (usually < 300 mm), only heat vulcanization lagging can be selected, which can avoid the influence of the tension of the rubber sheet on the adhesion; the price of heat vulcanization lagging is low.
Disadvantages: The pulley needs to be disassembled and transported to the manufacturer for heating and vulcanization in a vulcanization tank, high time and transport costs ; Lagging rubber surface is prone to aging ; Time-consuming and labor-intensive maintenance
Cold bonding pulley lagging
Advantages: can be installed or maintained onsite, without removing the pulley, greatly save downtime and maintenance time; The lagging rubber has good performance of wear resistance and aging resistance.
Disadvantages: High requirements for the installation or maintenance site environment; high requirements for operators; Not suitable for smaller diameter pulleys.
Weld (Bolt) on lagging rubber
Advantages: The lagging pad can be prefabricated to the size of the pulley and can be quickly installed by welding or bolting; easy installation and maintenance ; short downtime.
Disadvantages: The steel retainer and fixing bolts used are easy to corrode and wear.
